It's gonna happen either way. Part of me wants to see it for the excitement and Pacquiao getting revenge would be sweet. Another part of me thinks that enough is enough. These guys are gonna end up permanently hurting eachother. They should just take some easy fights (or at least Pacquiao should) and retire. They have too much pride / ego though.

They both have eachother figured out to some degree or else they wouldn't have close fights, so it just feels like they will both end up punch drunk if they continue battling it out. I like them both and hold no grudges, I would like to see them both hang 'em up.

No it would literally prove nothing, if Pacquiao KO'd Marquez in 1 round it would be because Marquez is 40 and shot and if Marquez KO'd Pacquiao again then it's be 'well he was already damaged goods from the last fight...Pacquiao is done'

The 4th fight really was the moment where Marquez showed that he was the 'better man' during their fights and the convincing KO should help him erase the memory of those painful SD losses. Won't be long before we another Vazquez Marquez 4 kind of fight if they continue going at it.

All four fights went Juan way another would be the same with a fifth ,all Pac would need to do was survive for 12 rounds so Arum can have his hand in this to win a decision. Pac would get another gift ,they want this fight to make the Mayweather fight its all about $$$$$$$$$ now ,a fifth fight isn't going to be anything new.
